Example 1
FIG. 1 is a flowchart illustrating a method of optimizing regeneration according to an embodiment of the present invention. As shown in FIG. 1, this regeneration optimization method may mainly include the following steps.

  In step 101, when receiving a request related to a multimedia resource from a client, a search is made as to whether the optimized playback parameters for the multimedia resource are stored.

  In step 102, if the optimized playback parameter is stored, the optimized playback parameter is sent to the client such that the client plays the multimedia resource according to the optimized playback parameter.

  Here, a client usually refers to a program or device that provides a user with a local service. The client in this embodiment refers to a reproduction program or device capable of reproducing multimedia resources. The playback device is not particularly limited, and may include an internet television, a computer, a tablet, a mobile phone, and the like. Multimedia resources are an integration of multiple types of media and may generally include various media types such as text, audio, video and images. The reproduction parameters may include image quality reproduction parameters and / or sound quality reproduction parameters. Specifically, the image quality reproduction parameters may include contrast, saturation, brightness, noise reduction, sharpness, motion compensation and the like. Sound quality reproduction parameters may include parameters such as surround sound and clarity.

  In one possible embodiment, the optimized playback parameters may include image quality optimized playback parameters and / or sound quality optimized playback parameters.

  Specifically, the optimized reproduction parameter refers to a reproduction parameter set to optimize the reproduction effect of the multimedia resource. For example, by setting the corresponding parameters such as contrast and saturation for the video resource, a better image quality reproduction effect can be obtained by making the video screen clearer or the color richer. By setting the corresponding surround sound mode to the audio resource, the audio of the video can be propagated through multiple channels to obtain a better sound quality reproduction effect. The optimized playback parameters may include both a corresponding image quality optimized playback parameter and a sound quality optimized playback parameter, and may include one of an image quality optimized playback parameter and a sound quality optimized playback parameter.

  The request may be associated with the multimedia resource in any suitable manner, as desired. For example, the request may include multiple forms such as an on-demand request for multimedia resources, or a request for obtaining optimized playback parameters for multimedia resources. The request may include multimedia resource identification information, such as information such as multimedia resource name and number.

  Specifically, when the multimedia resource is not stored in the client, the client needs to obtain both the multimedia resource and the optimized reproduction parameters related thereto from the server. In this case, the client sends an on-demand request for multimedia resources to the server. The server searches whether or not the optimized reproduction parameter related to the multimedia resource is stored, and when the optimized reproduction parameter is stored, the client reproduces the multimedia resource according to the optimized reproduction parameter And sending the multimedia resource and the optimized playback parameters to the client.

  Furthermore, when the multimedia resource is stored in the client, the client usually needs to obtain only the optimized reproduction parameters related to the multimedia resource from the server. In this case, the client transmits to the server a request for acquisition of the optimized reproduction parameter related to the multimedia resource. The server searches whether or not the optimized reproduction parameter related to the multimedia resource is stored, and when the optimized reproduction parameter is stored, the client reproduces the multimedia resource according to the optimized reproduction parameter Sending the optimized playback parameters to the client.

  In one possible embodiment, as shown in FIG. 2, the regeneration optimization method may further comprise the following steps.

  In step 201, optimized playback parameters for the multimedia resource are generated based on scene features included in the multimedia resource.

  In step 202, the optimized regeneration parameters are stored.

  There are many types of methods for generating optimized reproduction parameters related to the multimedia resource. For example, it may be obtained by manual testing and adjustment based on experience, or may be obtained by analysis calculation by a background application program. In the present embodiment, the generation method of the optimized reproduction parameter is not limited. Furthermore, after generating the optimized reproduction parameter for the multimedia resource, it is stored in the server.

  Furthermore, in one possible embodiment, as shown in FIG. 3, it is more practical to generate optimized playback parameters for the multimedia resource (step 201) based on scene features included in the multimedia resource. Can include the following steps.

  At step 302, a first optimized playback parameter is set for each of the first sub-segments, and based on the first optimized playback parameter and the first time information, an optimized playback for the multimedia resource is performed. Generate parameters.

  In the present embodiment, a scene refers to a scene composed of objects such as a person and an environment in a multimedia resource. The “scene features” in the present specification are features that can represent feature points of a scene, such as human object features (eg, clothing features, number of people features, etc.), environmental object features (sky, green spaces, special buildings, rain, snow, Clear, etc.), content features (eg, ideas, themes, effect features, etc., intended to be expressed by a scene), dynamic features (mainly, motion scenes, still scenes, etc.). The scene features included in the multimedia resource may be, for example, artificially identified or automatically identified by a program, and are not particularly limited in the present invention.

  In the present embodiment, the method of selecting the first subsegment from multimedia resources is not limited. For example, the first sub-segment may be selected based on thought features that the scene is to represent, and the first sub-segment may be selected based on the effect features that the scene is to achieve. The first time information may be the reproduction start / end time of each first sub-segment, or may be a reproduction period including the start / end time of each first sub-segment.

  Hereinafter, a movie will be described by way of example. The movie scene usually contains the ideas that the director tries to express. In order to convey the true meaning of the movie as precisely as possible, the first sub-segment is selected based on the scene features included in the movie. For example, based on the environmental characteristics of the scene, select a dark scene sub-segment, a hazy scene sub-segment, a rainfall or snow scene sub-segment, and start / end times of the three first sub-segments, eg, 8 : 02 to 9:15, 17: 38 to 19: 42, 45: 29 to 50: 22 can be recorded respectively (step 301). Optimized reproduction parameters are generated for each of the three sub-segments. For example, for a sub-segment of a dark scene, adjust the dynamic backlight to make the screen dark enough, for a sub-segment of a hazy scene, reduce the sharpness, for a sub-segment of a rain or snow scene , Can reduce the noise reduction function. The optimized reproduction parameters of the three first sub-segments are arranged in the order of start and end times 8:02 to 9:15, 17:38 to 19:42, 45:29 to 50:22 for the movie. An optimized regeneration parameter is generated (step 302). Here, on the movie playback time axis, the start and end times, for example, 8:02 to 9:15, 17:38 to 19:42, and 45:29 to 50:22 are each from the beginning of movie playback. Elapsed time until the start of reproduction or end of reproduction of one sub-segment. The optimized playback parameters for the movie are stored in the server (step 202). When a request from the client to play the movie is received, it is searched whether or not the optimized playback parameters for the movie are stored (step 101). The optimized playback parameters for the movie are sent to the client so that the client plays the movie according to the optimized playback parameters (step 102).

  According to the reproduction optimization method according to the embodiment of the present invention, the reproduction effect can be improved by making use of the advantage of hardware in the reproduction process of multimedia resources. Furthermore, the content of the entire multimedia resource can be evaluated, and the idea expressed by the screen can be emphasized to deepen the understanding of the screen content.

  Hereinafter, a television drama will be described by way of example. In television drama scenes, scene features such as clothes and palaces often appear repeatedly. In order to make the screen clearer, the colors richer, and the reproduction effect higher, a second sub-segment in which a specific scene feature repeatedly appears is selected from the television drama. For example, the second sub-segment in which the clothes of the leading character appear repeatedly is selected, and the start and end times at which each second sub-segment appears in each story, for example, the first story 5:02 to 6:09, 40:15 to 42 Record 12, 12, second episode 16: 09 to 18: 21, 18: 32 to 23: 20, etc. (step 401). Parameters such as contrast and saturation can be adjusted so that the color of clothes becomes richer for the second sub-segment in which the clothes of the leading part appear repeatedly. The optimized reproduction parameters of the second sub-segment which appears repeatedly are the start and end times at which each second sub-segment appears in each story, eg, first story 5:02 to 6:09, 40:15 to 42:12, It arranges in order of the 2nd talk 16: 09-18: 21, 18: 32-23: 20 etc., and generates the optimization reproduction parameter about each talk of the television drama concerned. Further, the optimized reproduction parameter related to each episode of the television drama constitutes the optimized reproduction parameter related to the television drama (step 402). Here, on the reproduction time axis of the television drama, the start / end time, for example, the first episode 5:02 to 6:09, 40:15 to 42:12 is the first episode of the television drama from the start of the episode The time elapsed from the start of playback to the end of playback of the two subsegments. The optimized playback parameters relating to the television drama are stored in the server (step 202). When a request to play the television drama from the client is received, it is searched whether or not the optimized reproduction parameter related to the television drama is stored (step 101). The optimized playback parameters for the television drama are sent to the client such that the client plays the television drama according to the optimized playback parameters (step 102).

  According to the reproduction optimization method according to the embodiment of the present invention, the reproduction effect can be improved by making use of the advantage of hardware in the reproduction process of multimedia resources. Furthermore, it may be set collectively for subsegments in which specific scene features repeatedly appear throughout the multimedia resource. For example, by performing parameter adjustment on clothes of a leading character that appears repeatedly in a television drama, a better image quality reproduction effect can be obtained by making the screen clearer or the colors richer.

When the content of the live broadcast program is, for example, a soccer game, the scene features can usually be grasped in advance. For example, many screens display green grass, and there are many fast moving scenes. For the relay program of the entire soccer match, optimized reproduction parameters for the live relay soccer match can be generated. For example, the parameters such as contrast and saturation are adjusted to the green grass to make the color more vivid. For fast moving scenes, the motion compensation function of the playback device can be turned on to make the screen clear and smooth and improve the playback effect (step 501). The optimized playback parameters for the live broadcast soccer game are stored in the server (step 202). When receiving a request from the client to relay live the soccer match live, it is searched whether or not the optimization reproduction parameter related to the live relay soccer match is stored (step 101). The optimized playback parameters for the live broadcast soccer match are sent to the client so that the client plays the soccer match according to the optimized playback parameters (step 102).

  Similarly, sound quality optimized reproduction parameters corresponding to a live broadcast concert may be generated. For example, a surround sound mode can be set. Sound quality may be adjusted dynamically individually or with image quality.

  According to the reproduction optimization method according to the embodiment of the present invention, the reproduction effect can be improved by making use of the advantage of hardware in the reproduction process of multimedia resources. Furthermore, reproduction parameters can be set for scene features set in advance. For example, by performing parameter adjustment on the green grass and fast movement of a live broadcast soccer game, the relay screen can be made colorful, clear, smooth and have a better image quality reproduction effect.
